APPARATUS FOR FORCING FLUIDS FROM WELLS.

Application filed March 12, 1926.

This invention relates to improvements in apparatus for forcing fluids from wells, es-

vice insertible within the tubing of a well,

said device being provided with means cooperating with said tubing for separating the rising oil or water into a plurality of streams.

A further object is to provide within the device, fluid pressure exiting means starting from a common source and leaving the device at a plurality of points. i

A still further ob'ect is the provision or means for automatically opening and closing said fluid pressure exiting means.

With these objects in view, together with others which will appear as the description proceeds, the invention resides in the novel .lormation, combination, and arrangement of parts, all as will be described more fully hereinafter, illustrated in the drawings, and particularly pointed out in the claims.

In said drawings:

Figure 1 is a somewhat diagrammatic view illustrating a well and its casing in section, depicting the positioning of my invention therein.

Fig. 2 is a transverse sectional view, somewhat enlarged, said section being taken substantially on the line 2-2 of Fig. 1.

F ig. 3 is an enlarged elevation of my device, partly in section, illustrating certain fluid pressure entering and exiting means; and

Fig. 4 is a transverse sectional view taken substantially on the line 44. of Fig. 3.

Those skilled in the art to which this invention appertains will at once recognize the familiar parts ot' the :urrangement used for recovering fluids remote from the surface oi the earth, said arrangement being illustrated in Fig. 1, wherein the numeral 5 denotes the casing of the well, (i the tubing arranged concentric therewith and carrying, intermediate its ends, the ordinary pumping arrangement denoted generally by the numeral 7. These *arious parts being old and well understood, a detailed description thereof hardly seems necessary.

Passing now to the subject-matter of the present invention, it will be observed, on

Serial No. 94,273.

inspection of Fig. 3, that my device, denoted generally by the numeral 10, comprises a body portion 11 having its lower part reduced in diameter to form a' somewhat elongated shank 12 which latter is provided with a threaded stub 13 for attachment to the pumping arrangement 7, (see Fig. 1).

Said body portion 11 is provided with a longitudinal bore 14: which extends substantially the entire length thereof, the upper portion being enlarged, as at 15, and thread ed for the reception of the air conduit 16, (see Fig. 1). Arranged exteriorly of said body portion are a plurality of longitudinal ribs 17, the outer periphery thereof snugly engaging the interior of the tubing 6 and thus presenting a plurality of spaces 18, the.

purpose thereof and their function being fully set forth hereinafter.

Disposed adjacent the bottom of said bore 14 are a plurality of openings 19 which extend upwardly and outwardly in the form of conduits 20 and finally emerge at the top surface of the ribs 1?. As noted in the drawings each rib carries a conduit 20. The tops of said conduits 20 are closed by shutters 21 hinged at 22 and being automatically operated by the passage of air therethrough.

In the operation of the device air under pressure is introduced through the pipe 16, which descends into the bore 14, enters the openings 19 and finally emerging from the conduits 20 at the top of the device.

The fluid in the bottom of the well is caught up by the suction of the compressed air exiting from the conduits 20, said fluid, of course, entering the tubing 6 by means of the apertures 6 therein and ascending through said tubing for final discharge. The operation of the air opens and closes the shutters or valves 21 and when dropped in Lil ill)

closed position by gravity, prevent the entrance of sand or other accumulations within the conduits 20 and bore 14.

My device is capable of insertion within a very small tubing and hence is especially adapted for small wells. Obviously the time and money saved by the use of a small well is a feature of some importance.

While the foregoing sets forth the preferred embodiment of my invention, it is. of course, to be understood that the same is susceptible of minor alterations and changes.

Having thus described my invention. I

claim as new and desire to secure by U. S.

Letters Patent 1. In a device of the character described, in combination with a well including a tubing, an elongated body portion having a plurality of ribs abutting said tubing and n-esenting spaces therebetween, said body portion being provided with a longitudinal bore and passageways leading from the base thereof and diverging to the top of said ribs.

2. In a device of the character described, in combination with a well including a tubing, an elongated body portion insertible within said tubing and having a plurality of ribs abutting said tubing and presenting spaces therebctween, said body portion being provided with a longitudinal bore terminating short of the base thereof and av plurality of passageways in comn'iunication with the base of said bore and extending obliquely upward longitudinally of said ribs and terminating at the upper face thereof.

3. In a device of the character described in combination with a well including a tubing and pumping means, an elongated body portion inseitible within said tubing and adapted to be secured to said pumping means, said body portion being provided with a plurality of ribs abutting said tubing and delining spaces therein and a longitudinal bore having passageways diverging urnyardly from the base thereof and terminating at the upper face of said ribs and means automatically opening and closing said passageways.

In testimony whereof, I afiix my signatme.
